Theoretical and Experimental Chemistry Aims and scope

Abstract

The surface ionization of triethylamine molecules (M) in accelerating fields of strength F from 2·104 to 4·106 V/cm has been studied under stationary conditions with the aid of mass spectrometry. The predominant formation of (M-H)+ fragment ions has been discovered. The logarithm of the relative intensity of the ion currents at T = const varies linearly with the value of √F. The temperature dependence of the ion currents I(T) at F = const, which are in good agreement with the experimental dependences and make it possible to determine the kinetic parameters of the reaction, have been obtained with the aid of the theory of monomolecular dissociation of molecules in the gaseous phase and the theory of surface ionization.
